(Connersville, IN)--Three high-ranking Carbon Motors executives claim that the company owes them more than $600,000 in back pay. According to a lawsuit that was filed through a Fayette County court Tuesday, the three all signed contracts that dictated that a substantial portion of their salaries were due no later than the first of March of this year. But, they say, those payments never came. And now, they’re suing. Keith Marchiando, Alan Bratt, and Trevor Rudderham all carried the title of executive vice president with Carbon Motors. None of the three are living in Fayette County. Carbon Motors has three weeks to respond. Even though Carbon Motors packed up and left Connersville earlier this year, they’re still registered for business in Indiana. CEO William Santana Li is now involved in a California company called Stealth.
